Mug(ぶんどる, Bundoru?), also known as Capture, Plunder, or Smash and Grab, is a combination of Fight and Steal, allowing the user to attack and attempt to steal an item in the same turn. Like its counterpart Steal, it is usually associated with the Thief class.

Mug, called Capture in the older translations, is the Level 6 ability of the Thief job class, learned for 150 ABP. The Thief Knife randomly attempts a steal when used with the Attack command. Mug will ignore any Added Abilities on the character's equipped weapon.

Locke Cole and Gogo can use Mug, also known as Capture, if they are equipped with a Brigand's Glove. Due to a bug the Brigand's Glove replaces any effect on the user's weapon, such as random instant death or defense-ignoring, with a Mug attempt. However, weapons that randomly cast spells still perform such after the steal attempt is made.

The Thief's Knife causes its user to attempt to steal when attacking at 50% rate. It can be equipped by Locke and Shadow. Harvester can use Mug on the party, but it works like Steal Gil as oppose to stealing items. If the monster(s) or the party escapes, the party loses the stolen gil. If the enemy is defeated and the battle is won, the party will gain the stolen gil.

There is a glitch involving Mug and the relic Master's Scroll, or any attempt to steal multiple items within a single turn. After having Locke use Mug while equipped with the Master's Scroll (or any character wielding two Thief's Knives), the first item stolen will always be stolen, but any items that would be stolen afterward will not be added to the player's inventory (unless the monster is alone). Any items stolen after the first item cannot be stolen again under any circumstances, as the first successful steal will count as a successful steal for any other enemies the unit targets during the attack, only the items are never obtained.

Mug is the Level 2 ability on the Steal Materia. It is the same as the Steal command with an added Attack. Mug replaces the Steal command and uses the same math as Steal does to steal from enemies, including the Sneak Gloves.

The Bandit can use the Mug command, stealing items from the inventory of, and causing damage to, one target. Shortly afterward, the unit will use its Escape command, the victim losing their item forever. There is a three-quarter chance they will use Mug, otherwise they will use Hold-up to steal gil instead. If the player kills the enemy before it has time to flee they will win back the stolen item.

Zack can use Mug with the Mug Materia. After spending a moment charging the attack, Zack attacks an enemy and attempts to steal from them. Mug requires no AP to use. Mug can be created through Materia Fusion by upgrading a Steal Materia.

Mug is a support ability the Guardian ForcesDiablos and Bahamut can learn for 200 AP. When equipped, the Attack command is changed to Mug. This is the only ability in the game which allows players to steal items from opponents; there is no base Steal ability.

MugDifficulty is often 128 or higher meaning a base Mug% of 50% or higher, which is further increased by the character's Spd. The enemies have four item "slots" in the game data and the item one obtains via Mug depends on which slot the character steals from. The lower slots contain common items, whereas higher slots usually contain better/rare items. If the character successfully mugs an enemy, the game decides which item slot's item the player gets by utilizing the game's random number generator (random value between 0 and 255).

If the player has the Rare Item party ability in effect, the probabilities are modified. Since it's impossible to get a value higher than 255 on the random number generator it's impossible to get an item from Slot 3 with Rare Item equipped, which means, counter-intuitively, Rare Item might prevent the player from obtaining the rarest items.

The Garment Grid Treasure Hunt grants the ability to Mug. The Grid is acquired when challenging Shinra to a game of Sphere Break; the player must make a combo with a border coin with Item or Rare Item trait. Shinra can only be played in Chapter 3 during Luca's Sphere Break tournament, or, if lost, during Chapter 5 in Luca's locker rooms.

Mug is a useful ability in that it grants the user AP for the action even when the steal fails, whereas a regular Attack command gives no AP. Mug is one of the few ways of granting the ability to physically attack to the White Mage, Black Mage and Songstressdresspheres.

Mug appears in Final Fantasy XIV: A Realm Reborn as a Rogue ability gained from a level 15 Class Quest. Mug delivers an attack with a potency of 140 to a single target and has a 90 second recast time. Enemies damaged by Mug have a small chance to drop a greater number of items when they are killed. Additionally if the Rogue has used Kiss of the Viper they healed for half of the damage dealt by Mug.

Mug is a level 20 Dirty Tricks ability for the Thief class, and caps at level 20. It allows the user to deal damage while stealing elementite from the target, but can only be used once per battle and up to three times a day.

Mug is the level 16 ability of the Thief class, learned for 380 AP. It requires 2 slots to equip and use, and when used the user will physically attack the target with a chance to steal that target's item as normal.
